Differential Pressure Sensor service buttons

During a reading Alarm state, pressing and immediately releasing the silence button clears the audio alert and stops the red LED from flashing, but does not acknowledge the alert in your OneVue account.

Audio alert resumes once the time period of the Resume Audio Alert setting has been reached. Audio alert settings are configured from a sensor's gateway profile.

Check-in button

Pressing and releasing the check-in button during normal operation initiates a check-in to OneVue. During a check-in, all logged readings are transmitted to OneVue and any pending updates are downloaded to the device. During an active check-in connection, additional pressing of the check-in button is ignored.

When the check-in button is pressed and released, the device emits a series of audio beeps indicating its connection sequence. When a device emits beeps as indicated below and displays Signal Ok, this indicates a successful check-in.

1 beep: device booted

2 beeps: device connected to network

3 beeps: device connected to OneVue

If a check-in fails, commonly due to the device cannot establish a network connection, all logged readings are stored in the device's non-volatile memory. If the number of failed check-ins exceeds the size of the non-volatile memory, the oldest readings are overwritten. Primex sensor devices store up to 4096 readings.
